The division of 0x80000000 by -1 gives FPE on both Intel and AMD Processors...

I have checked that with the following simple program on both Fedora core 3's
GCC 3.4.4 and debian sarge's gcc-3.3.5...

I also had someone check it with gcc 4.1.2 and FreeBSD too...

int divide(int a,int b)
{
  return a/b;
}

int main(void)
{
  return divide(0x80000000,-1);
}

and what I get is:

./test
Floating point exception

And GDB says "Program received signal SIGFPE, Arithmetic exception."
